Overexpression of 11β-Hydroxysteroid Dehydrogenase-1 in Adipose Tissue Is Associated with Acquired Obesity and Features of Insulin Resistance: Studies in Young Adult Monozygotic Twins
Abstract
11beta-Hydroxysteroid dehydrogenase type 1 (11beta-HSD-1) catalyzes the interconversion of inactive cortisone to active cortisol. Overexpression of 11beta-HSD-1 in murine adipose tissue results in glucocorticoid receptor (GR)alpha overexpression, central obesity, and insulin resistance. It is controversial whether 11beta-HSD-1 or GRalpha expression are increased in human adipose tissue in obesity. We studied effects of acquired obesity on 11beta-HSD-1 gene (real-time PCR) and protein (Western blotting) expression in sc adipose tissue in 17 monozygotic twin pairs aged 24-27 yr with a mean intrapair difference in body mass index (BMI) of 3.8 kg/m(2) (range 0.4-10.1 kg/m(2)). Intrapair correlations were calculated to study effects of acquired obesity on 11beta-HSD-1 expression. Western blot analysis of adipose tissue homogenates identified approximately 50- and approximately 68-kDa proteins specific for 11beta-HSD-1. Both structural forms correlated positively with 11beta-HSD-1 mRNA concentrations. Intrapair differences in 11beta-HSD-1 mRNA, and the 50- and 68-kDa proteins in sc adipose tissue correlated positively with those in BMI (kilograms per square meter) (r = 0.78 for 11beta-HSD-1 mRNA, P = 0.0002; r = 0.87 for the 11beta-HSD-1 50-kDa protein, P = 0.0003; and r = 0.62 for the 11beta-HSD-1 68-kDa protein, P = 0.033), total body fat (percent) (r = 0.65, P = 0.005; r = 0.83, P = 0.001; and r = 0.69, P = 0.013, respectively) and sc fat (cubed centimeters) (r = 0.66, P = 0.004; r = 0.94, P = 0.0001; and r = 0.71, P = 0.009, respectively). Furthermore, 11beta-HSD-1 mRNA and 50-kDa protein expression, but not 68-kDa protein expression, correlated positively with intrapair differences in intraabdominal fat mass (cubed centimeters) (r = 0.62, P = 0.008; r = 0.69, P = 0.013; r = 0.48, P = 0.112) and serum fasting insulin concentration (milliunits per liter) (r = 0.76, P = 0.0004; r = 0.60, P = 0.037; and r = 0.43, P = 0.160, respectively). Intrapair differences in GRalpha expression were significantly inversely correlated with those in BMI and total and sc fat mass. In conclusion, expression of 11beta-HSD-1 in sc adipose tissue is increased in human acquired obesity and is closely related to accumulation of sc and intraabdominal fat and features of insulin resistance.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
